I have a 360 stock rods (ARP waveloc bolts) stock crank (ARP main studs) forged piston, RPM proformer heads (ARP head studs) and RPM air gap intake . What I am wondering is will my bottom end setup hold 500hp with a 200 hp shot of nitrous. This is a street/stripe car so it won't be at the drag strip every weekend.
 
Not for long. Without the shot the crank and rods would probably live for a while if everything is spot on. But that 200hp shot might kill it all along with the block.
 
500 + 200, or 300 + 200? Sorry I wasn't sure what you've got...
 
So you're finding that you're a body with a measly 500hp isn't quite doing it for you on the street?
I'll never understand building a motor from the top down?
 
Why are you asking this question?.... if you have the know how to obviously build a 500hp small block, you would know that a stock cast crank and rods wouldn't hold up to 700hp with N2O. I am not a professional engine builder or anything, but hell, I even know that wouldn't survive. I wouldn't imagine the stock crank and rods would last with out the N2O.

Well the thing is I have heard of a few guys spray 200 hp on this type of setup, I was just wondering if anyone on here have tried it.

I'm going to say not for long as well. I don't think I would be brave enough to spray my forged bottom end with a 200shot on top of my 600hp. But my fear then would be more of a factory block issue.
Even at 700hp you could be pushing the limits of your block as well, let alone the rotating assembly. Of course the jury is still out on what power a smallblock can live at. If you've already had lots of over boring it certainly won't help.

I'd say its a gamble all around, but if you do spray it, keep us posted.
 
A forged crank and good rods are not that expensive.

What's the details on the motor? Cam specs and anything else you haven't shared yet. Curious what you got going on to start with.

You won't be making anywhere close to 500hp NA with that camshaft, no way, no how!
 
Dang, You guys and your laughing gas. All it does is destroy engines. If a 125 shot survives lets throw a 200 shot down it's throat. Soon you will be sweeping up your $5000 engine off the pavement. Just my opinion. Take it or leave it.
 
to be honest I think your building a bomb. hit it with 100 shot and fix the after effects .
i'm sure a weak link is just beyond the flywheel. thats if ya hook, if not then why 700hp
